Once upon a time I fixed a qbert bezel. Basically I started by coating with krylon triple thick. From there I carefully mixed acrylic paints to the correct colors I needed. Rather than paint on wich I was afraid would leave brush strokes, I basically dripped the paint on the areas I needed one drop at a time. This process took a few days since I had a number of colors to fill in. after letting dry for a couple days I once again coated with triple thick. BTW for the black areas I used an oil based krylon brand paint. Applied in the same manner as above. Worked great and made a bezel that most would have thrown in the trash look damn good.
As for where I bought it, krylon triple thick (spray can) home depot, krylon black (not spray can), home depot, acrylic paints, wal mart.
BTW the original coating with triple thick allows you to wipe away a mistake if you catch it quickly enough.
